UniUconvFromUcs

UniUconvFromUcs(uconvObj, ucsBuffer, ucsBufferLen, outBuff, outBuffLen, nonIdenticalConv)

Convert a UCS string to code page characters.

Parameters

The input buffer's length, in bytes.
outBuff - (void **) - output
The output buffer.
outBuffLen - (size_t *) - output
Number of code page character elements in the outBuff.
nonIdenticalConv - (size_t *) - output
Number of non-identical conversions.

Constants

Example Code

UconvObject uconvObj;
UniChar     ucsBuffer;
size_t*     ucsBufferLen;
void**      outBuff;
size_t*     outBuffLen;
size_t*     nonIdenticalConv;
integer     rc;
...
rc = UniUconvFromUcs(uconvObj, ucsBuffer, ucsBufferLen, outBuff, outBuffLen, nonIdenticalConv);

Notes

The sequence of the code page characters in ucsBuffer is converted into a sequence of Unicode characters in outBuff. The code page was set by UniCreateUnconvObject call in the UconvObject.

Conversion is only on bytes that convert. The process stops converting on the first non-valid byte. If the outBuff isn't large enough, conversion ends on the UniChar previous to any buffer overflow. outBuff is updated truncating the point of failure to the end and updating the outBuffLen to indicate the number of successfully converted elements.
